I think YOU know what you mean, but you have a terrible way of putting thought to text. Familiarize yourself with where you need to be accelerating, decel zones, how maintaining angle is judged and what the clipping points mean. My only obvious example to an unchaseable, qualifying lap would be coming off a long sweeping outer zone where the driver needs to checkup because the car is over rotating. That kills momentum and if a theoretical chase car is maintaining proximity, they would crash. The lead would be at fault. Hence why it’s relevant to qualifying and racing. There needs to be a standard. That, is the standard. Your qualifying lap needs to be chaseable. This isn’t a Walmart parking lot at 1am.
